Yokogawa MRT*A Terminal Board

Overview

The Yokogawa MRT16A is an industrial-grade I/O terminal board engineered for seamless integration with CENTUM VP, CENTUM CS 3000, and ProSafe-RS control systems. It provides a robust and organized wiring interface between field instruments—sensors, actuators, and switches—and system I/O modules, ensuring reliable signal transmission even in electrically noisy industrial environments.

Designed for precision and durability, the MRT16A simplifies installation, maintenance, and system expansion while maintaining signal integrity across analog and digital circuits.

FAQ

Q: Can the MRT16A handle analog and digital signals simultaneously?
A: Yes, depending on the variant, it supports both analog and digital I/O types.

Q: Is DIN-rail mounting standard for all MRT variants?
A: Some models use DIN-rail, others are panel-mounted. Check the variant specifications before installation.

Q: What is the maximum voltage supported by MRT terminals?
A: Typically, digital circuits operate at 24 VDC; analog ranges depend on the connected I/O module.
